The Petty knife can perform versatile functions and is the favorite go-to knife of many Japanese chefs.

In fact, in most fine restaurants only the head chef is allowed to use it, therefore the Kiritsuke is often considered to be a symbol of expertise and status.

KOTAI’s Kiritsuke is made of Japanese 440C, a premium steel that balances a high carbon content for hardness, sharpness and edge retention with the perfect amount of chromium to prevent corrosion.


Slicing, rock chopping, dicing, julienne, brunoise... Great food starts with precise cutting. The acute 15 degree edge ensures that you never bruise delicate ingredients and always preserve their freshness.
AUS-10 has more than 3x the carbon content than other premium steels. The blade, heat treated to HRC 62 hardness, keeps its razor-sharp edge cut after cut.
The perfect weight distribution and hand-polished pakkawood handle have been designed for you to cut effortlessly through the toughest food without compromising on comfort.
